A 1/8 half-angle wedge is mounted at 0 angle of attack in the test section of a supersonic wind tunnel. The wave angle (θ) of oblique shock waves formed from the leading edge of the wedge is measured to be 41.8°.
a) Calculate the exit Mach number (5 pts) and exit-to-throat area ratio (5 pts) of the nozzle.
b) Calculate the local pressure (5 pts), local temperature (5 pts), local density (5 pts), and local velocity (5 pts) at the exit of the nozzle.
